(5) If the ambient temperature is other than

75F, see table 3-4 for correct voltage output.

(6) If voltage is not within limits specified,

replace regulator and repeat test.

(7) Increase load with carbon pile until

minimum rated current output is reached. Voltage at

output terminal should be at least 13 volts but should not

exceed maximum limits in table 3-4.

b. Removal.

(1) Disconnect cable from alternator at

connector.
